Semantic Web And Peer-To-Peer

It is the purpose of this book to acquaint the reader with the needs of joint Semantic Web and Peer-to-Peer methods and applications, in particular in the area of information sharing and knowledge management where we see their immediate use and benefit.For this purpose, we start with an elaborate introduction to the overall topic of this book. The introduction surveys the topic and its subtopics, represented by four major parts of this book, and briefly sorts all individual contributions into a global perspective.The global perspective is refined in an introductory section at the beginning of each part.

The Semantic Web and Peer-to-Peer are two technologies that address a common needat different levels:
- The Semantic Web addresses the requirement that one may model, manipulate and query knowledge and information at the conceptual level rather than at the level of some technical implementation. Moreover, it pursues this objective in a way that allows people from all over the world to relate their own view to this conceptual layer. Thus, the Semantic Web brings new degrees of freedom for changing and exchanging theconceptual layer of applications.
- Peer-to-Peer technologies aim at abandoning centralized control in favor of decentralized organization principles. In this objective they bring new degrees of freedom for changing information architectures and exchanging information between different nodesin a network.
- Together, Semantic Web and Peer-to-Peer allow for combined flexibility at the level of information structuring and distribution.
